Moving route guidance device, moving body, and moving route guidance method

Abstract

The moving route guidance device includes: display control means configured to execute display control to change at least one of a content and a display position of the route guidance image based on position information of the moving body. The route guidance image includes: a plurality of route identification images respectively corresponding to the plurality of the movable routes that are close to each other and displayed in a manner to correspond to a visually recognized position relationship between the plurality of the movable routes by the driver or a predetermined reference position; and an route instructing image displayed in association with the route identification image that corresponds to the moving route guided by the route guidance image of the plurality of the movable routes.

The invention claimed is: 
     
       1. A moving route guidance device that displays a route guidance image for guiding a driver in a moving body to a moving route in a predetermined display area at front in a moving body advancing direction by an image projection optical system, the moving route guidance device comprising:
 display control circuitry configured to execute display control to
 change at least one of a content and a display position of the route guidance image based on position information of the moving body, wherein 
 
 the route guidance image includes:
 a plurality of route identification images respectively corresponding to a plurality of movable routes that are close to each other and displayed in a manner to correspond to a visually recognized positional relationship among the plurality of movable routes by the driver or a predetermined reference position; and 
 route instructing images displayed in association with the route identification images that correspond to a moving route guided by the route guidance image of the plurality of movable routes, 
 
 the display control circuitry is further configured to execute the display control to display a route identification image, of the plurality of route identification images, at a position which overlaps lines of vision of the driver with respect to a movable route of the plurality of movable routes, and 
 the position is in the predetermined display area when a visually recognized position of the movable route by the driver does not overlap the predetermined display area. 
 
     
     
       2. The moving route guidance device according to  claim 1 , further comprising:
 a sensor configured to capture a front view of the moving body in an advancing direction of the moving body, wherein 
 the display control circuitry is further configured to execute the display control based on the position information and an image captured by the sensor. 
 
     
     
       3. The moving route guidance device according to  claim 1 , wherein the display control circuitry is further configured to display the route identification image, which corresponds to the moving route guided by the route guidance image, of the route identification images in a manner to be more emphasized than the other route identification images. 
     
     
       4. The moving route guidance device according to  claim 1 , wherein the display control circuitry is further configured to display the route identification image such that visibility of the route identification image is lowered as a distance between each movable route of the plurality of movable routes and the moving body is reduced. 
     
     
       5. The moving route guidance device according to  claim 1 , wherein the route instructing image is another image that separates from the plurality of route identification images. 
     
     
       6. The moving route guidance device according to  claim 1 , wherein
 the plurality of route identification images is formed by branch images branched for each of the plurality of movable routes, and 
 the route instructing image is an arrow image that continues to the route identification image corresponding to the moving route guided by the route guidance image. 
 
     
     
       7. The moving route guidance device according to  claim 1 , further comprising:
 the image projection optical system. 
 
     
     
       8. A moving body comprising the moving route guidance device according to  claim 7 . 
     
     
       9. A moving route guidance method for displaying a route guidance image for guiding a driver of a moving body to a moving route in a predetermined display area at front in a moving body advancing direction by an image projection optical system, the moving route guidance method comprising:
 obtaining position information of the moving body; and 
 executing display control to change at least one of a content and a display position of the route guidance image based on the obtained position information, wherein 
 the route guidance image includes:
 a plurality of route identification images respectively corresponding to a plurality of movable routes that are close to each other and displayed in a manner to correspond to a visually recognized positional relationship among the plurality of movable routes by the driver or a predetermined reference position; and 
 route instructing images displayed in association with the route identification images that correspond to a moving route guided by the route guidance image of the plurality of movable routes, 
 
 the executing the display control further includes displaying a route identification image, of the plurality of route identification images, at a position which overlaps lines of vision of the driver with respect to a movable route of the plurality of movable routes, and 
 the position is in the predetermined display area when a visually recognized position of the movable route by the driver does not overlap the predetermined display area.
